Murf Voice Cloning API vs Smallest.ai Instant Voice Clone

Murf Voice Cloning API 40

Read as a model, on the lines Murf's text-to-speech listing and the other hosted speech models use (recency 30, dated releases 10, deprecation notice 10, support 15, issues 10, SDKs 15, health 10). The 1 October check used the tool lines. Murf's site wasn't re-read on 5 November, since its terms bar bots and automated access. The newest dated change this listing has read is the 20 July 2026 changelog entry, the Gen2 streaming deprecation notice, per the 1 October check, 108 days ago (10). No release touching cloning in the 90 days from 7 August that we could read. murf-mcp 0.1.14 (20 August) adds setup for a docs server and has no cloning tool (0). The Gen2 streaming notice gave 27 days, with no stated notice period (5 of 10). Public changelog and a Discord channel named in the docs (10 of 15). SDK issues weren't read, since GitHub's pages answer 403 in this session (3 of 10). The Python SDK is still 2.3.0 of 5 March 2026 by its tags. It streams speech from a clone but has no cloning methods (5 of 15). CI runs mypy and pytest on every push, Python 3.8 and later (7 of 10). 10+0+5+10+3+5+7 = 40.

Smallest.ai Instant Voice Clone 72

Read as a model, on the lines the other hosted cloning listings use (recency 30, dated releases 10, deprecation notice 10, support 15, SDKs 15, health 10). The models changelog has entries dated 29 October 2026 (30). Entries on 21, 24, 26, 28 and 29 October and in September (10). The deprecation page dates each retirement, such as lightning-v3.1 and its clones on 30 November 2026 with steps to migrate, though when the clone retirement was first announced wasn't found (7 of 10). Public changelog, support@smallest.ai and a Discord server, with no evidence read of how they answer (10 of 15). smallestai on PyPI released 5.12.3 to 5.14.0 between 1 and 7 October 2026, from a repository under fern-demo. The npm package is stale (10 of 15). Package repositories weren't cloned (5 of 10). 30+10+7+10+10+5 = 72.

Murf Voice Cloning API 0

Per the 1 October check, not re-read on 5 November, since Murf's terms bar bots and automated access to its site. No x402, MPP or L402 (0). Cloning is Enterprise-only and priced by contract, which counts as contact sales even though Falcon 2 speech has a public list rate (0). No free cloning (0). A person has to talk to sales before the endpoints work (0).

Smallest.ai Instant Voice Clone 20

No x402, MPP or L402 (0). Per-character TTS prices are public, about $0.175 per 10,000 characters on Lightning v3.1, but no price per clone is published and the models pricing table marks voice cloning No on pay as you go, against the docs (10). The agents pricing page states $10 in free credits, and whether a card is needed wasn't established (10 of 20). A person signs up in a browser and creates the key in the dashboard (0). 0+10+10+0 = 20.

Murf Voice Cloning API 83

Atlassian status page at murf.statuspage.io, titled Murf Status, with API and Studio components and incident history back to February 2024, read on 5 November 2026 (20). The 1 October check missed it. Its four posted incidents end on 22 September 2025, so the 90 days from 7 August are clean (30). Concurrency published, 5 Falcon 2 requests on US-East and 2 on other endpoints for Free and Pay as You Go, custom on Enterprise, per the 1 October check, not re-read on 5 November (15). The cloning docs don't mention 429 or backoff. The official Python SDK's README documents automatic retries with exponential backoff on 408, 429 and 5xx, which cover the speech calls a clone is used with but not the cloning endpoints (8). No idempotency key for clone creation (0). No SLA published (0). Instant cloning is generally available to Enterprise workspaces, per the 1 October check (10). 20+30+15+8+0+10 = 83.

Smallest.ai Instant Voice Clone 65

Graded on the hosted cloning API with the hosted lines. status.smallest.ai is the vendor's own status page with components per region and a dated incident feed (20). The feed, read on 6 November, has dozens of automated outage alerts on the API components in the 90 days from 8 August, most a few minutes long, and a cluster across every API region from 13 to 17 September. The 60-day uptime bars read 99.790 per cent for API USA and 99.849 per cent for API Global. No single outage of an hour was found, but repeated wide outages read as one major episode (10). Rate limits are published for TTS (one concurrent request, 100 a minute on pay as you go), while the per-organisation clone limit has no number (10 of 15). The limits page says to handle 429 gracefully and the clone errors say to retry a timeout, with no Retry-After, backoff figures or idempotency key (5 of 15). The pricing table lists an Enterprise SLA of 99.99 per cent (10). Instant cloning carries no beta label (10). 20+10+10+5+10+10 = 65.

Murf Voice Cloning API 84

Per the 1 October check, not re-read on 5 November, since Murf's terms bar bots and automated access to its site.

The API reference pages are generated with typed fields, enums and error schemas, but no OpenAPI file was found linked from the docs or llms.txt (5 of 25). llms.txt and a Markdown copy of every page (10). The guide says when to use the Pro pool, how to check modelIds before synthesis and why a mismatched clone returns empty audio, while the reference still names the retiring default (14 of 20). model and language are enums validated by the server, with required displayName and file, a 5 MB limit and MIME types listed, and tags as a comma-separated string (12 of 15). Examples in curl, Python and Node.js and a table of seven error cases with causes (14 of 15). Paths under /v1, a deprecation page with dated statuses and a models changelog with entries on 21, 24, 26, 28 and 29 October 2026 (15). 5+10+14+12+14+15 = 70.

Murf Voice Cloning API 35

Per the 1 October check, not re-read on 5 November, since Murf's terms bar bots and automated access to its site. Graded for voice cloning, with consent and misuse controls in place of the read-only line and training and retention of voice data in place of the prompt-injection line, since the API returns audio and IDs rather than third-party text. api-key header plus a token endpoint for short-lived client tokens, no scopes found (25 of 30). No consent step, only a written rule to clone voices you own or have documented consent for, and no watermark found (0 of 20).

No security.txt, bug bounty, SOC 2 or trust centre found (0 of 20).

Smallest.ai Instant Voice Clone 48

Graded for voice cloning as the other listings in this category, with consent and misuse controls in place of the read-only line and training and retention of voice data in place of the prompt-injection line. Plain bearer keys, shown once, revocable, with rotation guidance and no scopes. Short-lived access tokens are refused on the cloning endpoint (20 of 30). No consent or verification field.

A usage dashboard, with no audit log found (5 of 15). A valid security.txt naming security@smallest.ai and a HIPAA business associate agreement page. The trust centre didn't answer through our proxy, so no certification was confirmed first-hand, and no bug bounty was found (8 of 20). 20+6+9+5+8 = 48.
